# Commission Regulation (EU) 2017/2400 of 12 December 2017 implementing Regulation (EC) No 595/2009 of the European Parliament and of the Council as regards the determination of the CO2 emissions and fuel consumption of heavy-duty vehicles and amending Directive 2007/46/EC of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011 (Text with EEA relevance), Division 3.4.1.2

Extent: E+W+S+N.I.

The following system requirements shall be met by a single torque meter by calibration:
i.. Non linearity: < ± 6 Nm
ii.. Repeatability: < ± 6 Nm
iii.. Crosstalk: < ± 1 % FSO (only applicable for rim torque meters)
iv.. Measurement rate: ≥ 20 Hz
where:
‘Non linearity’ means the maximum deviation between ideal and actual output signal characteristics in relation to the measurand in a specific measuring range.
‘Repeatability’ means closeness of the agreement between the results of successive measurements of the same measurand carried out under the same conditions of measurement.
‘Crosstalk’ means signal at the main output of a sensor (My), produced by a measurand (Fz) acting on the sensor, which is different from the measurand assigned to this output. Coordinate system assignment is defined according to ISO 4130.
‘FSO’ means full scale output of calibrated range.
The recorded torque data shall be corrected for the instrument error determined by the supplier.
